The thermal behavior within housing obeys both to natural heat transfer processes as well as thermophysical properties of the different materials constituting the housing particularly those concerning to the envelopes such as: Ceiling, Walls and Floor. All materials are sensitive to the thermal effects and define in part the ranges of temperature values inside housing. Of a great importance also are the conditions of orientation of the house and number of openings that in turn generate air flows modifying the thermal inside conditions. On this work we analyze the influence of the envelopes on the thermal comfort inside housing, based on a computer thermal analysis and considering the material thermal properties. At the same time, we proceed to involve an experimental analysis recording temperatures gradient on different places and times inside a real house. It was performed the comparison of these results, observing in addition the regulatory standards on this matter in Mexico. The Computer Modeling was carried on through Ansys software, the developed macros includes a friendly environment during the whole process.
